(e-mail: [email protected]) Abstract.-Neoleucinodes silvaniae, u. sp., from Colombia, is described. The larvae feed on the fruit of wild Solanum lanceifolium Jacq. Adults and larvae of the new species are figured. The new species is compared to Neoleucinodes elegantalis (Guenee), a major pest of tomatoes throughout South America. Neoleucinodes prophetica (Dyar), N. imperialis (Guenee), and N. torvis Capps are reported from Colombia for the first time.

In order to establish an effective control method against this pest, a study of the abundance of larvae L .orbonalis according to phenological stages of eggplant was conducted in the locality of Azaguié, in Guinean area of Côte d'Ivoire. Investigations were carried out from October 2013 to June 2014. The method used were to a weekly counting of larvae on three varieties of the specie Solanum th aethiopicum ( Djamba F 1, Kotobi and N'drowa issia) from 21 day after transplanting until the end of the harvest. All varieties recorded larvae during three phenological stages. The three varieties recorded more larvae at the fruiting stage than at the flowering and stage before flowering with 123.38 ± 4.09; 114.33 ± 4.22 and 106.18 ± 4.25 larvae per 24 plants respectively on Djamba F 1 , Kotobi and N’drowa issia.

  • Crambidae Biosecurity Occurrence Background Subfamilies Short Description Diagnosis
    Diaphania nitidalis Chilo infuscatellus Crambidae Webworms, Grass Moths, Shoot Borers Biosecurity BIOSECURITY ALERT This Family is of Biosecurity Concern Occurrence This family occurs in Australia. Background The Crambidae is a large, diverse and ubiquitous family of moths that currently comprises 11,500 species globally, with at least half that number again undescribed. The Crambidae and the Pyralidae constitute the superfamily Pyraloidea. Crambid larvae are concealed feeders with a great diversity in feeding habits, shelter building and hosts, such as: leaf rollers, shoot borers, grass borers, leaf webbers, moss feeders, root feeders that shelter in soil tunnels, and solely aquatic life habits. Many species are economically important pests in crops and stored food products. Subfamilies Until recently, the Crambidae was treated as a subfamily under the Pyralidae (snout moths or grass moths). Now they form the superfamily Pyraloidea with the Pyralidae. The Crambidae currently consists of the following 14 subfamilies: Acentropinae Crambinae Cybalomiinae Glaphyriinae Heliothelinae Lathrotelinae Linostinae Midilinae Musotiminae Odontiinae Pyraustinae Schoenobiinae Scopariinae Spilomelinae Short Description Crambid caterpillars are generally cylindrical, with a semiprognathous head and only primary setae (Fig 1). They are often plainly coloured (Fig. 16, Fig. 19), but can be patterned with longitudinal stripes and pinacula that may give them a spotted appearance (Fig. 10, Fig. 11, Fig. 14, Fig. 22). Prolegs may be reduced in borers (Fig. 16). More detailed descriptions are provided below. This factsheet presents, firstly, diagnostic features for the Pyraloidea (Pyralidae and Crambidae) and then the Crambidae. Information and diagnostic features are then provided for crambids listed as priority biosecurity threats for northern Australia.

Anteparra, 1 Kelly Vargas y 2Lida B. Granadosa RESUMEN Es el primer registro para el Perú del perforador del fruto N. elegantalis en la cocona Solanum sessiliflorum Dunal, conocida también como tupiro, topiro, cubui, tomate de indio, peach tomato, manzana o melocotón del Orinoco. En el Perú no ha sido reportada anteriormente atacando a cultivo alguno. Durante los años 2008 y 2009 hemos observado a esta especie en campos comerciales de cocona en la Provincia de Leoncio Prado, departamento de Huánuco en el Alto Huallaga. El daño producido es la destrucción de frutos, porque la larva se alimenta dentro de estos, lo que provoca la pérdida de la calidad de los frutos. Aunque se la puede hallar durante todo el año en la cocona, hemos observado que en el Alto Huallaga durante los meses de setiembre y diciembre, que los frutos infestados alcanzan entre 4 y 5 %, que la mayor población de N. elegantalis se presenta durante el aumento de las lluvias. Aunque su población es bastante baja, esta se incrementa durante los meses de setiembre a diciembre. Los adultos miden alrededor de 25 mm de envergadura de las alas, estas son de color blanco hialino. Su importancia radica en su condición de plaga cuarentenaria, en los eventuales países importadores. Palabras clave: Primer registro; Neoleucinodes elegantalis; Perforador del fruto de cocona; Cocona.

  • First Record of the Genus Tetracona Meyrick (Lepidoptera, Crambidae) from China, with Description of a New Species

ZooKeys 941: 101–105. https://doi.org/10.3897/zookeys.941.49559 Abstract The genus Tetracona has two species with an Australian distribution. The present study aims to record the genus from China for the first time and to add a third species,T. multispina Jie & Li, sp. nov. to the genus. The new species can be distinguished from the congeners by the antemedial line connecting the postme- dial line near the dorsum in the hindwing, and the phallus with a cluster of spine-like cornuti in the male genitalia. Images of the habitus, tympanal organs and male genitalia are provided for the new species. Keywords China, Pyraloidea, Spilomelinae, snout moths, Tetracona, taxonomy Introduction The genus Tetracona was erected by Meyrick in 1884 with Aediodes amathealis Walker, 1859 as type species (Meyrick 1884). Then it was defined as a junior synonym of Agrotera Schrank, 1802 based on the external characters by Hampson (1899).

  • Phylogeny and Nomenclature of the Box Tree Moth, Cydalima Perspectalis (Walker, 1859) Comb
    Eur. J. Entomol. 107: 393–400, 2010 http://www.eje.cz/scripts/viewabstract.php?abstract=1550 ISSN 1210-5759 (print), 1802-8829 (online) Phylogeny and nomenclature of the box tree moth, Cydalima perspectalis (Walker, 1859) comb. n., which was recently introduced into Europe (Lepidoptera: Pyraloidea: Crambidae: Spilomelinae) RICHARD MALLY and MATTHIAS NUSS Museum of Zoology, Koenigsbruecker Landstrasse 159, 01109 Dresden, Germany; e-mails: [email protected]; [email protected] Key words.

The box tree moth, Cydalima perspectalis (Walker, 1859) comb. n., is native to India, China, Korea, Japan and the Rus- sian Far East. Its larvae are a serious pest of different species of Buxus. Recently, C. perspectalis was introduced into Europe and first recorded from Germany in 2006. This species has been placed in various spilomeline genera including Palpita Hübner, 1808, Diaphania Hübner, 1818, Glyphodes Guenée, 1854 and the monotypic Neoglyphodes Streltzov, 2008. In order to solve this nomen- clatural confusion and to find a reasonable and verifiable generic placement for the box tree moth, the morphology of the above mentioned and some additional spilomeline taxa was investigated and their phylogeny analysed. The results show that C. perspec- talis belongs to a monophylum that includes three of the genera in which it was previously placed: Glyphodes, Diaphania and Pal- pita. Within this monophylum, it is closely related to the Asian Cydalima Lederer, 1863. As a result of this analysis, Sisyrophora Lederer, 1863 syn. rev. and Neoglyphodes Streltzov, 2008 syn.
